The reaction of RuCl3(NO)(PPh3)2 or RuCl3(NO)·H2O with Ph2P(CH2)nP(O)Ph2 (n = 1, 2, or 3) yields trans-RuCl3(NO)[Ph2P(CH2)nP(O)Ph2]2. Depending on conditions {RuCl2(NO)[Ph2PCH2P(O)Ph2]2}Cl, which contains one chelating and one monodentate ligand, can also be obtained. Reactions of RuCl3(NO)[Ph2PCH2P(O)Ph2]2 with AgBF4 form {RuCl2(NO)[Ph2PCH2P(O)Ph2]2}BF4, which contains the same cation as {RuCl2(NO)[Ph2PCH2P(O)Ph2]2}Cl, and RuCl(NO)[Ph2PCH2P(O)Ph2]2}(BF4)2, in which both ligands chelate. The reaction of RuCl3(NO)[Ph2P(CH2)2P(O)Ph2]2 with AgBF4 has led to {RuCl2(NO)[Ph2P(CH2)2P(O)Ph2]2}(BF4), where one ligand chelates and the second is monodentate, and to{RuCl2[Ph2P(CH2)2P(O)Ph2]2}(BF4)2, a Ru(III) complex that no longer contains an nitrosyl ligand. With the exception of trans-RuCl3(NO)[Ph2P(CH2)3P(O)Ph2]2 and {RuCl2(NO)[Ph2PCH2P(O)Ph2]2}(BF4) crystal structures of these compounds have be obtained. |
